A few issues: I cannot connect to the internet, I can't upgrade to WSL2

[drpeppercan]

I installed Ubuntu with LXDE, and that works to some extent.
But some things are not working.
Aside of not having access to the internet, I cannot run Software. It says:
"Sorry, something went wrong: Failed to connect to system D-Bus: Could not connect: No such file or directory"

Also, Advanced Network Configuration in menu://applications/Preferences won't run.

This is what I got when running "ifconfig" to check the network connectivity:

lo: flags=73<UP,LOOPBACK,RUNNING> mtu 1500
inet 127.0.0.1 netmask 255.0.0.0
inet6 ::1 prefixlen 128 scopeid 0xfe<compat,link,site,host>
loop (Local Loopback)
RX packets 0 bytes 0 (0.0 B)

wifi0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.2.38 netmask 255.255.255.0 broadcast 192.168.2.255

RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

I haven't touched the Firewall, maybe that's the problem. I just don't know exactly which apps to let through nor how exactly.
And even though my Win10 version is 20H2 (OS Build 19042.844), and I installed both "wsl_update_x64.msi", and "Windows10Upgrade9252.exe" Powershell still says that I am running WSL 1!

I hope the sum of all these issues will hint you as to what should be my next step.

Thanks in advance
